Question

What is the equation of the line that passes through the points (15, 9) and (-2, 9)?

y =9
y = -11/6x + 9
y = -17
7 = 6x + 11

Answer 1

Answer: y = 9

Explanation:

We see that both of the given coordinate points have the same y-value. This means that this line does not have a slope and is simply y = 9.

To confirm our answer, we can use the slope formula. This finds the change in y over the change in x. This gives us a slope of 0.

`\displaystyle (y_(2) -y_(1) )/(x_(2) -x_(1) ) =(9-9)/(-2-15)=0`
